sketch_Front and back upper half

Just did a bit more rough skethcing. Though when I draw the lines they aren't confident strokes. If anything they are just like chicken scratches which is probably something I'm going to have to work on.

I am adding in images of muscle anatomy and looking at Ecorche mainly on pinterest.http://www.pinterest.com/koivit/echorche/

I was heavily inspired by Scott Eatons 3D sculpt of Ecorche.

Roughing in the shapes

So currently I am now using mudbox just to sketch in the basic over all shapes of the muscles. I'll later go back and smooth in and add in more detail. I don't plan on painting it. I just wanna know where the muscles go for both male and female. Later on I plan on doing a blood elf chick but I don't know what I want her to be like. A mage? Villager? Warrior? For now I just want to focus on anatomy first.
